It feels so weird being flat down there, it feels so tight and empty to have no dick. You couldn't tell anyone, your mom had taken away internet before and it was two weeks before you got it back last time. You looked out your apartment window, the city was the same, you couldn't notice any different buildings, the world was pretty much the same just with genitals swapped.
You feel the need to piss and walk over to the bathroom. You instinctively reach for your dick before remembering that there isn't one there. You remember that you can't stand while peeing without a dick, if you're going to miss one thing from having a penis it'll be pissing with it.
You pull your panties down and sit on the toilet. You start voiding yourself a urine and it feels so strange. You're used to having pee come from your penis place, it's not supposed to be coming from between your legs. The difference in sensation is fascinating. You feel less in control of the stream, it's just a strange feeling.
After you're done pissing you realize you're turned on, all this thought of vaginas makes you think of boys. You pull out your phone but realize you don't want to look at boys with dicks. Thinking for a seconds you find a porn site specifically for trans boys, that way you'll be able to see men with vaginas. You realize that because you still aren't attracted to penises your dating pool is limited to trans men.
Looking at pictures of boys you try to start to masturbate. It feels weird to be horny but not have an erection. You don't really know where to start without a dick. You stick a finger in your vagina, it feels so alien to have a hole there, but it also feels good.
Wiggling around inside yourself you realize you're feeling a lot of pleasure. You're masturbating, with a vagina. You start feeling inside yourself more, turned on by the strange sensations. You eventually reach a powerful orgasm, and soon realize that you can have another right afterwards, an intense pleasure reverberates through your body until finally you finish.
You definitely want to get back to the normal world, but you can live like this for now.
